MINNESOTA v a WINDOW CONSTRUCTION Application filed April 7,

T heinve'ntion further aims to provide, in y a manner as hereinafter set forth, means for use in connection with windows for eliminating' the commonly used parting stops which always are a source of trouble, either by 001- and arranged to provide athoroughly efficientweather stripping medium to exclude air, dust and moisture. i v y A further object of the invention is to provide, in a manner as hereinafterset forth, a thoroughly efficient weather stripping me- Q diuln for use in Connection with windows,

and so constructed and arranged as *toelimrelative thereto. I s

Further objects of the invention are to pro vid'e,-in a manner'as hereinafter set fortln in window construction means forthe purposes referred to and which is simplein its construction and. arrangement strong, durable,

compact, thoroughly eiiicient in its use, convveniently released to permit for readily shift.- mg the sashes to and from normal position,

9 quickly installed with respect to a/ window frame and window sashes, automatically locking the sashes in nermal and-suspended positions. and comparatively inexpensive to manufacture. 1

lVith the foregoing and-other objectsin' view, the inventionconsists of the novel construction, combination and arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings, wherein isshown an embodiment throughout the severalviews lecting of paint or varnish or by the warp- I edge of the rail- Therail 4: is also formed 3 1931.

Associated with each element 31 is a releasing member 44 therefor and which when active provides for the shifting of the inner end-of element 31 towards the inner end of element 30 against the action of the arm 24- of theelement 21. The member 44 includes a shank 45 of rectangular contour and which terminates at its inner end'into a rectangular head 46 provided with an opening 47,

' through which extendsthe angle shaped end which such member is arranged.

element 48 therefor and associated'with each I of the members 44 arranged in the lower sash "is an actuating element 49 therefor.

Each of the actuating elements are vertically shiftable and arranged on the inner sides of the sashes. The element 48 is positionedin convenient reach. 7

Each actuating element includes arectangular plate 50 provided witha centrally dis- 'posed oval shaped slot 51 atits longitudinal "median and at a point between its transverse center and upper end, a pair of spaced aligning oval shaped slots 52, 53 in proximity to.

its "lower end and between the longitudinal median of the plate and the side edges of'the latter, and a rectangularslot 54 positioned in proximity to its upper'end at apoint between the longitudinal medianof the plate and inner side edge thereof. A shifting member 44 extends through slot 54 and has a loose fit therein; The plate 50 is slidably connectedto the sash by headedholdfast devices 53 extending through slots'51, 52 and 53. On the vertical shift'of plate 50 it carries member 44there= with and pulls thelatter to act on element 31 to shift its rear end towards element 30.

Associated with eachextension 18 and overlapped by the latter is a weather strip form- ;ing element55 consisting of a plate 56 which is secured to. the outer side portion of the other side edge ofa. sash and side rail, one

side of plate 56 has projected therefrom at right angles thereto and into anextension 18 a U-shapedportion 57. At the other end of plate 57 is .an angleshapedflange-58 which engages in thesash. a. p

The actuating element 48 has extending therefrom a handle, or finger and thumb grip 59 for vertically shifting the plate 50 of element 48.

Theactuatingelement 49 has its plate 50 provided with an outwardly directed right angularly disposed notched arm 60 to which is loosely coupled a handle bar. Secured to the lower sash is a bracket 62 which is notched v and loosely coupled to handle bar.

The. extensions 18, and portions 57 .inrcon nection with the strips 17 coact to provide a weather stripmedium. The elements 55 are constructed of metal and are secured to a sash and by this arrangement if the sashes shrink they will have noeifect uponthe interfitting tightengagement between the exten sions 18 and portions 57. The strips 17 are so secured in position that the, inner corners thereof. will bite intothe window frame.
